Procedural Shaders - How Do They Work?

Recommended Posts

  • Topic Author
  • Hey Rantin Al - great contribution - I especially like the author's comments at the top of each shader panel - maybe we could convince him to show a few examples of each shader applied to some geometry.

    Thanks!

    Glad to see you guys find the reference useful.

    Jim, I think the way it is set up with the same sphere is the best use for comparing each noise. It's really up to the user to experiment with different geometry. That's where the fun begins. wink.gif

    Cheers, Alan.

  • You're right - I've just got this obsession on creating ocean surfaces - I get really close but it's still looking like an ocean with an oil spill floating on top.

    Thanks!

    Have you seen Paul Selhi's 'Ocean Tutorial' over at SFX?

    There was also a good Ocean Shader tutorial in the September issue of 3DAttack.

    Cheers, Alan.

  • Yes Alan - thanks - Paul's ocean shader is the best one I have - using fusion and layering - my original question was more on the line of hoe did Paul come up with that combination of parameters to create such a great shader? Was it months of experimenting or is there a general approach I'm not aware of.

    I've talked to quite a few guys on the forums with this and similar questions - I'm seriously thinking of putting a dvd-book series together loaded with contributing authors - I know I'd buy them - not expensive, but in color, spiral bound so they lay flat, and a dvd loaded with lessons, tips, and video tutorials...

    I just have to get the time and techniques down first - small obstacle called "reality"... haha

    I just looked on SFX site and could find no trace.

    SFX > Downloads > C4D > Scenes (page 3).

    You will have to register to download.

    There is also a topic on the scene and tutorial. Just search "Ocean".

    Cheers, Alan.
